Installation
Loudspeaker placement in a room can greatly affect
performance. The XRT28 Loudspeaker is designed for
both Music and Home Theater Systems. The optimal
method for selecting speaker locations includes the use of
a real time spectrum analyzer operated by an experienced
system installer. An uncompromising installation would
take into consideration the floor, wall and ceiling
coverings, the type and placement of furniture and can
even include the architectural design of the room and its
construction materials. In those instances where placement
in the room is fixed an enviromental equalizer may be
needed to restore proper musical balance.
Placement near a wall, corner, floor, ceiling or any in-
tersecting surfaces will reinforce or diminish some bass
frequencies. The bass frequencies that are altered by place-
ment in a particular location is dependant on the dimen-
sions of the room. If professional measurement equipment
is not available, test the various Loudspeaker locations by
playing music with continuous bass, setting up the speak-
ers and listening to them from the main listening spot.
Move the Loudspeakers to an alternate location and repeat
the listening, paying attention to how the bass qualities and
response levels change. Do not assume the loudest bass is
best; rather listen for booming (a lack of articulation), as
well as a balance over the whole spectrum, to assure the
bass will not drown out the other parts of the music. Ex-
periment with various Loudspeaker positions until the lo-
cation that sound best is found.
The XRT28 Column’s
Smooth Frequency Re-
sponse may be altered by
large object(s) located in
sound waves path or by
locating the column too
close to a side wall.
There should be an unob-
structed area in front of
the column of at least 30
degrees either side from
the center axis for the
best performance. Refer to figure 16.
Locating Loudspeakers for use in Home Theater
In a Home Theater application, the placement of Left and
Right Front
Loudspeakers can be
limited by such
considerations as the size
and location of the video
monitor. The locating
suggestions in the “for
use in a Music System”
section below can still be
helpful as a starting
place. Refer to figure 17.
Locating Loudspeakers for use in a Music System
When used in a Music System the distance between the
Loudspeakers and the
listener to the
Loudspeakers should
form an equilaterial or
acute isosceles triangle.
If the speakers are too far
apart relative to the
listener, some imaging
can be lost. Refer to
figure 18.

Optional Feet
16. Two sets of optional feet (eight Tiptoes and eight
Glides) are supplied with the XRT28 Loudspeaker
System. Refer to figure 15. To
prevent crushing carpet use
the Tiptoe Spikes; to protect
non-carpeted flooring use the
Chrome Glides. Both the
Glides and Tiptoes have a
threaded shaft and locking nut
that screw into the tapped
holes in the bottom of the
XRT28’s base rails. The feet can be independently ad-
justed to compensate for uneven flooring.
17. Stand the Column upright.
